Analysis of the development trend of 18650 lithium battery

At present, the technical application of lithium batteries in energy storage is mainly centered on the power grid base station backup power supply, home optical storage systems, electric vehicles and charging stations, power tools, home office equipment and other fields. During the '13th Five-Year Plan' period, my country's energy storage The market will take the lead in the field of public utilities, penetrating from the power generation and transmission side to the user side. Lithium battery big data statistics show that the application volume of lithium battery energy storage market in 2017 is about 5.8Gwh, and the market share of lithium ion batteries in 2018 will continue to maintain a trend of steadily increasing year by year. The 18650 lithium battery is increasing steadily, and the power 18650 is in a good situation. Lithium-ion batteries can be divided into consumption, power and energy storage according to application scenarios. Nowadays, power lithium batteries and energy storage lithium batteries are highly valued in the industry. According to the forecast of authoritative experts, the proportion of power lithium batteries in all lithium battery applications in my country is expected to rise to 70% by 2020, and power batteries will become lithium The main force of the battery. The lithium battery industry is developing rapidly, and the primary reason is that the policy promotes the development of the new energy automobile industry. In April 2017, the Ministry of Industry and Information Technology of the People's Republic of China also mentioned in the latest 'Mid and Long-term Development Plan for the Automobile Industry' that the production and sales of new energy vehicles will reach 2 million by 2020, and strive to account for more than 20% of the production and sales of vehicles by 2025. . It can be seen that environmental protection industries such as new energy and green energy saving will become important pillar industries of society in the future. In the future trend of power battery technology, Sanyuan is becoming a big trend. Compared with lithium cobalt oxide, lithium iron phosphate and lithium manganate batteries, ternary lithium batteries have the characteristics of high energy density, high voltage platform, high tap density, good cycle performance, and electrochemical stability, which are improving the battery life of new energy vehicles. It has obvious advantages in mileage, and it also has the advantages of relatively large output power, good low-temperature performance, and adaptability to all-weather temperatures. For electric vehicles, undoubtedly, consumers are mostly concerned about its endurance and safety. The ternary lithium battery is obviously a better choice. The rapid increase in the demand for electric vehicles has led to a substantial increase in the demand for power lithium-ion batteries, making them the main force driving the growth of the lithium-ion battery industry.
